Description
[technical field]
The present invention is a kind of turbulent and boiling combined-circulation fluidized bed refuse incinerator, belongs to the refuse treatment plant field.
[background technology]
Now low, the complicated component of China's rubbish ubiquity refuse classification degree, water content is big, calorific value is low etc. is unfavorable for aptitude to burn.Rubbish is sent into burner hearth by charging gear in traditional circulating fluid bed garbage furnace.Because traditional burner hearth all is upright burner hearth, rubbish under the gravity effect directly to the whereabouts, cause rubbish enter behind the incinerator various complicated ingredients can not be in very short time after-flame, and its moisture height, after going into stove, need to absorb a large amount of heats and be used for evaporating wherein moisture, this makes that combustion stability can not get ensureing, it is excessive the operational factor fluctuation usually to occur, be in operation to mix and burn a large amount of auxiliary fuels such as coal, and in moisture bigger season, mix the burning auxiliary fuel and also be difficult to guarantee smooth combustion, need to reduce the operation of burning amount.Simultaneously, because the particularity of fuel, the incinerator combustion product complicated component that is in operation produces a lot of different chemical reactions under the different temperatures environment, is in operation to be prone to high temperature slagging scorification, dust stratification etc. and to be unfavorable for the incident moved.In addition, incinerator is in operation owing to the flue gas flow rate height, and particle concentration is big, and its back-end surfaces wearing and tearing are bigger.
[summary of the invention]
Be prone to temperature instability in the incinerator in the prior art in order to overcome, it is abundant inadequately to burn, mix coal ratio height, the big deficiency that waits of power consumption the invention provides a kind of novel turbulent and boiling combined-circulation fluidized bed refuse incinerator, by increasing turbulence chamber, make rubbish just drying and pyrolysis fully before entering boiling-house, thereby make incineration firing abundant, that has reduced coal effectively mixes burning ratio, effective wearing and tearing and the etching problem that alleviates high temperature slagging scorification and back-end surfaces.For this reason, the present invention is by the following technical solutions:
Turbulent and boiling combined-circulation fluidized bed refuse incinerator, comprise burner hearth and cyclone separator, the bottom of described burner hearth is provided with boiling-house, be provided with ebullated bed in the boiling-house, have the rubbish feeding mouth at the middle part of burner hearth, the top and the cyclone separator of described burner hearth are connected, the bottom of cyclone separator is connected with boiling-house by material returning device, the outlet on cyclone separator top links to each other with the flue that is furnished with heating surface, it is characterized in that: be provided with the turbulence chamber that can make rubbish tilt to transfer between described rubbish feeding mouth and the boiling-house, described turbulence chamber comprises air distribution plate, is furnished with the blast cap of arranging and be communicated with extraneous and turbulence chamber at a certain distance on the air distribution plate.The setting of turbulence chamber can make the time of staying of rubbish in burner hearth increase, what is more important, and the high temperature wind energy of introducing from blast cap makes the rubbish dispersion at turbulence chamber's regional movement, dry, pyrolysis, and the rubbish of process pyrolysis enters boiling-house with the two-forty fired state.The heat energy that carries in the heat energy and the circulating ash of boiling-house burning generation acts on turbulence chamber's rubbish with reverse strong convection form, promotes the physical change and the chemical reaction of waste component.The setting of turbulence chamber makes boiling-house can set up balanced, stable temperature field, aerodynamic field, realizes fully burning under the air-breathing of certain excess quantity.
Turbulent and boiling combined-circulation fluidized bed refuse incinerator, it is characterized in that: the outlet on cyclone separator top links to each other with the upper end of flue gas sedimentation dual firing chamber, described flue gas sedimentation dual firing chamber is an exhaust gases passes that is surrounded by fin panel casing, the lower end of flue gas sedimentation dual firing chamber links to each other with the bottom of rising chamber, the rising chamber is the exhaust gases passes that is furnished with heating surface, and the top of rising chamber links to each other with flue.High-temperature flue gas carries fine particle and enters flue gas sedimentation dual firing chamber by cyclone separator.Uncombusted particle burning after-flame in flue gas sedimentation dual firing chamber.Flue-gas temperature owing to the heat exchange decrease to some degree, has been avoided high temperature slagging scorification district and high temperature corrosion district in flue gas decline process.The rising chamber is the exhaust gases passes that is furnished with heating surface, flue gas is risen be connected with the back flue, and can make flue gas cooling and cooling.
Turbulent and boiling combined-circulation fluidized bed refuse incinerator is characterized in that: flue gas sedimentation dual firing chamber lower end links to each other with an end of the impacting type separator that the pipe of having loose bowels forms, and the other end of impacting type separator links to each other with the bottom of rising chamber.Lower end, rising chamber is provided with particle and reclaims bucket.Flue gas is behind process impacting type separator, and flow velocity reduces, the wearing and tearing that effectively alleviated back-end surfaces; Bulky grain is separated, and the particle that separates reclaims bucket by particle and collects, discharging regularly.
Turbulent and boiling combined-circulation fluidized bed refuse incinerator is characterized in that: blast cap is the segment type structure.The segment type blast cap can solve the long-pending and problem such as not smooth that flows of the extension of rubbish in motion process.
Turbulent and boiling combined-circulation fluidized bed refuse incinerator is characterized in that: the turbulence chamber bottom is provided with air compartment.Air compartment can make the intersection high temperature wind of friction speed enter turbulence chamber with stable speed.
Turbulent and boiling combined-circulation fluidized bed refuse incinerator is characterized in that: the turbulence chamber bottom is provided with three air compartments of equidistant arrangement.A plurality of air compartments are set, can make high temperature wind enter turbulence chamber with more stable speed.
Turbulent and boiling combined-circulation fluidized bed refuse incinerator provided by the invention, design by architecture advances, further reinforcement is fully burnt and has been solved and mixes coal than high shortcoming, saved the energy, alleviated the high temperature slagging scorification of heating surface, alleviate the wearing and tearing of back-end surfaces, improved incinerator separate unit day output.
